The IWC Da Vinci collection was launched in 1969 with a hexagonal Beta 21 quartz model (3501) and it was not until 1985, with the launch of the perpetual calendar chrono 3750 that we saw the round case with hinge lugs appear. This automatic time only IWC Da Vinci SL, reference 3528, with its stainless steel mesh bracelet was launched in 1998 and was discontinued in 2003. It doesn't get any better, treat yourself today.
